South Australia has announced plans to hold a tender for the “next generation” of renewable energy technologies, including projects that provide “firming” for current and pending wind and solar projects, bulk energy storage, and bio-energy. Premier Jay Weatherill says developers will be invited to apply for a share of the $150 million Renewable Technology Fund, or at least the estimated $130 million that is left after the commitment to the Tesla big battery to be built in Jamestown by December 1.
